《A Macrocycle Based on a Heptagon-Containing Hexa-peri-hexabenzocoronene》 was written by Jimenez, Vicente G.; David, Arthur H. G.; Cuerva, Juan M.; Blanco, Victor; Campana, Araceli G.. Category: iodides-buliding-blocks And the article was included in Angewandte Chemie, International Edition in 2020. The article conveys some information:
A cyclophane is reported incorporating two units of a heptagon-containing extended polycyclic aromatic hydrocarbon (PAH) analog of the hexa-peri-hexabenzocoronene (HBC) moiety (hept-HBC). This cyclophane represents a new class of macrocyclic structures that incorporate for the first time seven-membered rings within extended PAH frameworks. The saddle curvature of the hept-HBC macrocycle units induced by the presence of the nonhexagonal ring along with the flexible alkyl linkers generate a cavity with shape complementarity and appropriate size to enable π interactions with fullerenes. Therefore, the cyclophane forms host-guest complexes with C60 and C70 with estimated binding constants of Ka=420±2 M-1 and Ka=(6.49±0.23)x103 M-1, resp. As a result, the macrocycle can selectively bind C70 in the presence of an excess of a mixture of C60 and C70.1-Bromo-4-iodobenzene(cas: 589-87-7Category: iodides-buliding-blocks) was used in this study.
1-Bromo-4-iodobenzene(cas: 589-87-7) is mainly used as the OLED pharmaceutical intermediate, as reagent for in situ desilylation and coupling of silylated alkynes, as substrate in copper-free Sonogashira coupling in aqueous acetone..Category: iodides-buliding-blocks It is also used in synthesis of β,β,dibromostyrenes, as starting reagent in the total syntheses of ent-conduramine A and ent-7-deoxypancratistatin (alkaloids)
